As well as adding coordination costs in
separation and coordination optimization schemes :-) .

I am not aware of any real cost associated with reactive
generation for typical power plants. This feature was
implemented to allow the OPF to be used to clear markets where
there were non-zero offers for reactive generation.

Dear Dr Zimmerman,
Does the 'basekV' column in the mpc.bus matrix play
any role in the solution that matpower produces, or is
it only for presentation ?
So for example, 10 buses have 138kV and 5 others have
233kV as basekV.
Secondly, as it is possible to set in the objective
function the $/MVARh cost of generating Q, I would like
to ask about the realism of such a thing.
In reality, is there any such thing as cost of
generating a MVAR ?
As far as I know, the fuel cost is always in terms of
$/MWh.
Thank you

MATPOWER does not include any functions to do this
automatically, but it is trivial with a few lines of
Matlab code using 'find' with a condition that
compares the actual MVA flows to RATE_A and actual bus
voltages with VMIN/VMAX.

Dear Dr Zimmerman,
I am doing research related to power
security. I am simulating a
contingency by setting the branch
status to 0. But I want to know the
matpower can print out all the
branches that have cross the limit and
the buses voltage which are violated
after running power flow
Thank you
It
has no effect whatsoever on
the power flow results. It can
simply be useful for
manipulating data or reporting
data by region.

Dear Dr
Zimmerman,
Could you
please explain to
me how the
division of the
system in areas,
in case ieee24 and
generally all
cases, affects the
power flow and the
reliability
analysis?
Regards,
Angelina
